    /**
	 * Sets the type of metadata to use. Metadata is encoded in JSON, and each property
	 * in the JSON will become a property of the element itself.
	 *
	 * There are four supported types of metadata storage:
	 *
	 *   attr:  Inside an attribute. The name parameter indicates *which* attribute.
	 *          
	 *   class: Inside the class attribute, wrapped in curly braces: { }
	 *   
	 *   elem:  Inside a child element (e.g. a script tag). The
	 *          name parameter indicates *which* element.
	 *   html5: Values are stored in data-* attributes.
	 *          
	 * The metadata for an element is loaded the first time the element is accessed via jQuery.
	 *
	 * As a result, you can define the metadata type, use $(expr) to load the metadata into the elements
	 * matched by expr, then redefine the metadata type and run another $(expr) for other elements.
	 * 
	 * @name $.metadata.setType
	 *
	 * @example <p id="one" class="some_class {item_id: 1, item_label: 'Label'}">This is a p</p>
	 * @before $.metadata.setType("class")
	 * @after $("#one").metadata().item_id == 1; $("#one").metadata().item_label == "Label"
	 * @desc Reads metadata from the class attribute
	 * 
	 * @example <p id="one" class="some_class" data="{item_id: 1, item_label: 'Label'}">This is a p</p>
	 * @before $.metadata.setType("attr", "data")
	 * @after $("#one").metadata().item_id == 1; $("#one").metadata().item_label == "Label"
	 * @desc Reads metadata from a "data" attribute
	 * 
	 * @example <p id="one" class="some_class"><script>{item_id: 1, item_label: 'Label'}</script>This is a p</p>
	 * @before $.metadata.setType("elem", "script")
	 * @after $("#one").metadata().item_id == 1; $("#one").metadata().item_label == "Label"
	 * @desc Reads metadata from a nested script element
	 * 
	 * @example <p id="one" class="some_class" data-item_id="1" data-item_label="Label">This is a p</p>
	 * @before $.metadata.setType("html5")
	 * @after $("#one").metadata().item_id == 1; $("#one").metadata().item_label == "Label"
	 * @desc Reads metadata from a series of data-* attributes
	 *
	 * @param String type The encoding type
	 * @param String name The name of the attribute to be used to get metadata (optional)
	 * @cat Plugins/Metadata
	 * @descr Sets the type of encoding to be used when loading metadata for the first time
	 * @type undefined
